A pressure-relieving safety assembly, comprising a sleeve (108) and collar (104), protects against human injury and loss of life by blocking flow of fluid from a ruptured high pressure conduit (114) and provides pressure relief for escaping fluid. This pressure-relieving assembly includes a sleeve (108) that encircles the high-pressure line and is secured to, at one or both ends of the line, a coupling. The sleeve is secured to the coupling (s) by a collar (104) having raised portions that provides a path for fluid that has escaped from the conduit at a burst or pin-hole failure location, to flow towards the ends of the conduit, indicating to the user that a conduit failure has occurred. The sleeve lowers the fluid velocity while the path provided by the collar prevents the fluid pressure from building up behind the sleeve. |
